FROM OUR USERS

Hundreds of composers around the world choose GMT to transform their composing workflow within Sibelius!

Graphical MIDI Tools is an innovative plug-in that has improved my workflow a lot. It easily fills the gap between Sibelius and the DAW by being capable of drawing MIDI CC data into your written score which can later be carried over to the sequencer. To me, it’s one of those plug-ins that make working with Sibelius even more efficient. ”

The GMT plugin allows me to do everything in Sibelius, without having to use a DAW. For me, it was a complete game changer as you can now automate everything as easily as you can in a DAW.”

GMT is an amazing plugin which lets you work inside Sibelius in a DAW-like way, and it integrates perfectly as a lower MIDI editing zone into the main software. I use this plugin frequently in my daily workflow for finer adjustments, and when I import my project into my DAW, I find all of the changes carried over too. In this way, I save lots of time for my daily workflow and I can concentrate more on the artistic challenges instead of dealing with the technical difficulties.”

FEATURES

ADJUST THE START AND DURATION OF A NOTE'S SOUND

With GMT, you can fine-tune the start position and duration of each note in your music.

These changes will only affect the playback, and NOT the written score, allowing you to refine your MIDI mockup to your needs.

Draw MIDI automation curves for any controller

Take your MIDI mockups to the next level by inserting your own custom MIDI CC (Continuous Controllers) or pitch bend atomation curves.

All with your mouse in an easy, graphical way!

Edit Note velocities in a graphical way

Get the exact dynamics values your passage needs based on your favourite library.

With GMT you can indicate which velocity you want a note to have, or leave the velocity unset to let the playback engine decide.

Edit the tempo curve (BPM) graphically

With the tempo track, you can now graphically edit the tempo curve.

Create custom ritardandos, accelerandos, or subtle changes in tempo to achieve a more human-like performance.

Add Hidden "phantom" notes / key switches module

With the "phantom" notes module, you can insert and edit MIDI hidden notes which are only performed by the playback engine (via MIDI commands), and do not affect written score at all.

This allows you to recreate performances whenever notation is not 100% explicit, like for example on a harp glissando indication.

"Phantom" notes are also great for triggering key switches, if your library supports them.

FREQUENTLY ASKED QUESTIONS (F.A.Q.)

Q: Are MIDI edits preserved when exporting the score as a MIDI file?

A: Yes! One of the great advantages of GMT is that all your edits (automation curves, velocities, hidden notes, etc.) are stored in the MIDI export file. Should you want to continue your workflow in a sequencer/DAW, all of your MIDI edits will be imported as well."

 

Q: If I open my score in a friend's computer without GMT, will my MIDI edits be present?

A: Yes! GMT stores all your edits as text commands above the staff, or as note properties. These are saved within the Sibelius file. If you open your score on a computer without GMT, Sibelius will still play all of your edits, but you will not be able to edit them in the graphical manner that GMT offers.

 

Q: Does it work with NotePerfomer?

A: Yes!. Not only does it work with it, but it complements it perfectly. NotePerfomer's artificial intelligence will decide how to play your score with outstanding results in the great majority of cases.

Every now and then, when you might want to manually adjust certain MIDI parameters, or draw a custom automation curve, or even add hidden notes is where GMT comes in: to help you polish your mockup and get great sounding results."
